CVE-2018-0786 →

📋 Description

A security feature bypass vulnerability exists when Microsoft .NET Framework (and .NET Core) components do not completely validate certificates. An attacker could present a certificate that is marked invalid for a specific use, but the component uses it for that purpose. This action disregards the Enhanced Key Usage taggings. The security update addresses the vulnerability by helping to ensure that .NET Framework (and .NET Core) components completely validate certificates.
